Ingredient review
Hydrogenated Poly(C6-12 Olefin)
INCI: HYDROGENATED POLY(C6-12 OLEFIN)
A lightweight, non-greasy synthetic emollient that helps products spread smoothly without clogging pores.
In plain English
This is a man-made oil-like ingredient that makes skincare products feel silky and smooth on your skin. Unlike heavy natural oils, it doesn't leave a sticky or greasy residue, so it's great for people who want hydration without the heavy feel. It's often used in moisturizers, sunscreens, and makeup to improve texture and spreadability.

Quick decision guide
Easy yes for most routines
Hydrogenated Poly(C6-12 Olefin) is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrogenated Poly(C6-12 Olefin).
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic hydrocarbon oil created by polymerizing and then hydrogenating medium-chain olefins (C6 to C12). It is chemically similar to mineral oil but with a more controlled molecular structure, resulting in a lighter, less greasy feel.
How it works
It sits on the surface of the skin, forming a thin, breathable film that reduces water loss (acts as an occlusive) while also making the product feel silky and easy to spread. Because it's non-volatile, it stays on the skin to provide lasting softness without evaporating.
Pros
Lightweight and non-greasy
Unlike heavier oils, this ingredient leaves a silky, barely-there feel, making it ideal for daytime use or under makeup.
Low pore-clogging risk
Rated low on the comedogenic scale, so it's unlikely to cause breakouts, even for acne-prone skin types.
Cons and cautions
Synthetic origin
Derived from petrochemicals, which may be a concern for those seeking natural or eco-friendly formulations.
Limited environmental data
There is less publicly available research on its biodegradability and long-term environmental impact compared to plant-based emollients.
Best for
- People with oily or combination skin who want hydration without greasiness
- Anyone looking for a lightweight, non-comedogenic emollient in moisturizers or sunscreens
Use caution if
- Those who strictly avoid synthetic or petroleum-derived ingredients
Usage tips
Safety summary
Hydrogenated poly(C6-12 olefin) is considered safe for topical use in cosmetics. It has a low irritation and comedogenic profile, and no significant safety concerns have been reported in routine use. However, as with any synthetic ingredient, individuals with extremely sensitive skin should patch-test new products.
Research notes
Research on this specific ingredient is limited, but it belongs to a well-studied class of synthetic hydrocarbons used in cosmetics for decades. Safety assessments by industry panels (e.g., CIR) for similar polyolefins support its safe use at typical concentrations.
Common label clues
- Typical concentration
- 1% to 10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. It is not a restricted ingredient, but like all cosmetic ingredients, it must be used in accordance with good manufacturing practices.
- Common uses
- Moisturizers, Serums, Sunscreens, Makeup primers, Lip products
- Environmental note
- As a synthetic hydrocarbon, it is not biodegradable in the same way as plant oils. However, its low concentration in rinse-off products may limit environmental exposure.
Good to know
- Hydrogenated poly(C6-12 olefin) is often used as a silicone alternative in 'silicone-free' formulations.
- It is considered safe for use in cosmetics by major regulatory bodies when used as intended.
